Detailed Description

This class implements a cone quadric.

Quadric for cone Q: Cone apex at: (m_x, m_y, m_z) Cone angle: a

[ 1 0 0 -m_x ]
[ 0 1 0 -m_y ]
[ 0 0 -tan^2(a) m_z tan^2 ]
[ -m_x -m_y m_z tan^2(a) (m_x^2 + m_y^2 - m_z^2 tan^2(a)) ]

Inside test: p^T * Q * p <= 0.0

Constructor & Destructor Documentation

Ocean::Geometry::Cone::Cone ( )

Creates an invalid cone.

Creates a cone by a given dihedral angle and a transformation.

Parameters

angle	Dihedral angle of the cone in radian, which is half of the aperture (aperture = 2 * angle)
transformation	Transformation to transform the default cone defined about the z axis
